Biography
Dr. Diana L. Ortiz-Montalvo is a Research Chemist with the Nano Materials Group in the Materials Measurement Science Division at the National Institute of Standards and Technology (NIST). Diana earned a B.S. in Chemistry from the University of Puerto Rico (San Juan, PR). As an undergraduate student, she worked on various research projects that focused on the chemical and physical characterization of aerosols. She earned her Ph.D. in Environ. Sci. from Rutgers University (New Brunswick, NJ). As a graduate student, she studied the formation of secondary organic aerosol through simulated cloud chemistry and droplet evaporation experiments. After earning her Ph.D., she began a two-year postdoctoral position as part of the NRC Research Associateship Program at NIST (Gaithersburg, MD). During her postdoc, she studied the morphology and composition of individual dust particles using advanced microscopy techniques. She reconstructed particles three-dimensionally to study the effect that particle shape and composition have on their optical properties. After her postdoc, Diana continued working at NIST as a permanent staff member developing methods for particle characterization. Currently, she is developing methods for detecting and characterizing microplastic and nanoplastic particles in complex matrices.
